CATALOGUE OF SPECIES OF CENTRARCHID:. 
I give below a catalogue of the species of Centrarchida, which appear 
to be valid, with their geographical distribution. Those of which I have 
not been able to examine specimens are indicated by astar(*). Several 
species, as Lepomis ophthalmicus Cope, Bryttus humilis Grd., are known 
only from specimens too immature for me at least to come to any cer- 
tain conclusion as to their true relations. 
The type-species of each genus is placed first; d. s. indicates doubt- 
ful species; d. g., doubt as to whether placed in the proper genus.
